background: induction of cellular response after exposure to electromagnetic fields is limited to coherent fields. an incoherent noise field is supposed to suppress the bioeffects of regular rf electromagnetic fields. the purpose of this study was to investigate the effect of gsm mobile phone-induced radiofrequency (rf) on the induction of oxidative stress in sp2/0 cell line. materials and meth...
Background: Over the past several years, the rapidly increasing use of mobile phones has raised global concerns about the biological effects of exposure to radiofrequency (RF) radiation. Numerous studies have shown that exposure to electromagnetic fields (EMFs) can be associated with effects on the nervous, endocrine, immune, cardiovascular, hematopoietic and ocular systems. In spite of genetic...

alzheimer’s disease, the most common type of dementia and a progressive neurode-generative disease, occurs when the nerve cells in the brain die. although there are medications that can help delay the development of alzheimer’s disease, there is cur-rently no cure for this disease. exposure to ionizing and non-ionizing radiation may cause adverse health effects such as cancer. looking at the ot...
background: the rapidly increasing use of mobile phones has led to public concerns about possible health effects of these popular communication devices. this study is an attempt to investigate the effects of radiofrequency (rf) radiation produced by gsm mobile phones on the insulin release in rats. methods: forty two female adult sprague dawley rats were randomly divided into 4 groups. group1 w...

Objective(s):Several studies have been carried out to investigate the effect of various nanoparticles exposed to radiofrequency (RF) waves on cancerous tissues. In this study, a colon carcinoma tumor model was irradiated by RF in the presence of gold-gold sulfide (GGS) nanoshells. Materials and Methods: Synthesis and characterization of GGS nanoshells were initially performed. CT26 cells were ...
There have been allegations in the media and in the courts that cell phones and other types of hand-held transceivers are a cause of cancer. There have also been numerous public objections to the siting of TV, radio and cell phone transmission facilities because of a fear of cancer induction. A recent publication in Radiation Research by Repacholi et al. (147, 631-640, 1997) which suggests that...
PURPOSE The biological effects of exposure to mobile phone emitted radiofrequency (RF) radiation are the subject of intense study, yet the hypothesis that RF exposure is a potential health hazard remains controversial. In this paper, we monitored cellular and molecular changes in Jurkat human T lymphoma cells after irradiating with 1763 MHz RF radiation to understand the effect on RF radiation ...
Fast growth of the number of mobile phone subscribers in Iran, over the last few years, is the reason for construction of more and more base stations (BTS) especially in residential areas. As the BTS antennas emit radiofrequency (RF) electromagnetic energy, so it is the main concern of general public about their health and safety. The aim of this research work is to assess public exposure...
